I-lAllEE-FASTENER.

Patented Dec.. 22, 191e..

To all whom t may concern Be it known that I, JOHN BROWN BAX- rien, citizen of the United States, residing at VVatervliet, in the county of Albany and IState of New York, have invented certain the primary object of the present invention to provide in connection with a fastener of the character stated novel locking means whereby the fastener, when positioned in place, will be prevented from becoming accidentally released from its fastening.

ln the application referred to a fastener is provided embodying arelatively fiat body part having a hook at one end and a pivoted lever adapted for connection with a link or the like for the usual chain of the fastener and being of a construction that when closed it willy assume a position overlying and against the bodyy part.

It is contemplated by the present invention to arrange in. operative association with the body part and lever, improved locking means, one that is highly efficient in use and so arranged with relation to the lever that `it does not interfere with the convenient manipulation of the latter when thesame is freed from said locking means.

lThe invention further includes novel supporting means for the locking member `whereby the latter' is firmly supported on the body of the fastener and arranged at a point where it oders the least obstruction.

More particularly the invention includes a body part comprising oppositely "disposed sides, a hook secured at one end of the body part, a lever pivoted adjacent the opposite end and between the sides of the body part, and a lock pivotally supported betweenl the sides of the body part and adapted to engage a cooperating` part intermediate kthe ends of said lever. j

Other and further improvements willl be appreciated from the detailed description to follow which for a clear understanding of the invention should beconsidered in connection with the accompanying drawings forming a part hereof and wherein is disclosed for the purpose of illustration a convenient embodiment of the invention.

fn the drawings: Figure 1 is a side view of the fastener applied to the collar; Fig. 2 lsan enlarged side elevation of the fastener wlth parts shown in section; Fig. 8 is a bottom plan view of the fastener; and Fig. 4 is a detail perspective view of the locking dog.

With more particular reference to the drawings a body part is provided, the same b eing relatively flat and comprising oppositelydisposed separated sides l. Adjacent one end of the body part is a suitable hook member the same comprising a main part 2 adapted to lie flat against one end of the body part and having a tongue 2a adapted to be positioned between the sides of the body part and an open mouth curved hook part 22 rlhe hook is conveniently secured, as by pintles or bolts 3 and 3a, and it will be appreciated that the tongue 2a of the hook affords av suitable spacing means for separating thesides l of the body part. An auxiliary spacing member 4 is arranged adjacent the upper edge at the opposite end of the body, the same beingsupported in place by a pintle da. A. suitable `lever is provided,

the same having a relatively thin tongue member 5 of a width to loosely lit between the sides of the bpdy part, the same being pivotally supported as by a suitable pintle 6 projecting between the sides 1 and passing through an aperture 5a in the tongue of the lever. The opposite end of the lever takes the form of a relatively wide smooth surfaced arm 7 free from connection and projecting to a point beyond the hook member 2b, the said varm being preferably curved so as to conform with the curvature of the edge of the body part as well as the surface of the hook member 2b as will be seen from reference to Figs. l and 2. The body part is provided with a cut-out portion 8 extending from the edge thereof inwardly, and the operating lever is provided with an inwardly projecting lip 9 formed of an integral projection of the lever and being of bendable metal whereby it is adapted to be bent t around an end bar 10 of a suitable link member 11 adapted for connection with a chain, as shown. It will be observed that the recess 8 provides a suitable seat for the reception of the lever formed by its means of connection with the link aforesaid.

los

' follows: 12 is a locking dog, the same having and when the locking edge 12C vet ya shank 122L apertured whereby it may be f sleeved upon a suitable pivot member or pin- .tle I preferably take advantage of the securing bolt 3 for this purpose. The tongue 2 of the hook is provided with a recessed part-'13 for the recept-ion of the shank 12a of the dog, lthe wall surrounding said recess forming means for limiting the back and forth movement of the dog, and the side walls surrounding the recess forming suitable guides in the pivotal or swinging movement of the dog.

A spring member is provided for normally holding the dog against one of the end walls of the recess, said spring member preferably taking the form shown at le, one end being coiled about the pivot bar or bolt 13 and the opposite end being extended to engage against an offset shoulder 15 on one side of the locking dog. The arm 7 of the lever is provided with an elon gated recess 7 a adapted for the reception of the dog 12. In operation the spring being arranged to hold the shank of the dog 12 adjacent one end wall of the recess an inclined or cam part 12b of the hook will ride over one of the end walls of the slot of the lever in the closing movement of the latter, passes through said slot of the lever the same will be moved by the action of the'spring into locking position over the outer surface of the lever adjacent the slot. When it is dey sired to operate the lever whereby to release the fastener it is only necessary for the operator to force the dog or hook 12 about its pivotal support against the action of the spring and to impart outward swinging n iovement to the lever when the dog will readily pass through the slot of the lever. It will be observed that the locking means does not interfere in the least with the ready and convenient operation of the lever since the dog is spaced from the free end or hand gripping part of the lever, and it will also be noted that the locking dog is so arranged on the hook that it oder-s no obstruction beyond the sides thereof and at the same time it is firmly supported by the` body of the hook.

I claim 1. vIn a hame fastener, the combination of a body part, comprising opposed side plates and spacing means, a hook secured at.l

one end to the body part, a lever having a tongue pivoted between the sides of the body part at the opposite end thereof, said lever having retaining means intermediate its ends, a link pivotally secured to the lever' by said retaining means, and a spring held pivotally mounted securing hook positioned on the body part and offering no obstruc- Lion beyond the sides of the body part, and said lever having a. recess intermediate its `ends adapted to receive said hook whereby the hook will retain the parts in position.

2. In a llame fastener, the combination of a body part having at one end a hook and a recess intermediate its sides adjacent the opposite end, a lever pivoted at one end in said recess and having a free end to engage over the body part and hook, said body part having a cut out part in one edge, means on the lever to engage a chain link or the like and adapted to engage in said cutout part, and a lock interposed between said body part and the lever intermediate its ends and spaced' from the free or hand engaging end of the lever.

3. In a haine fastener, the combination of a body part having at one end a hook and a recess intermediate its sides adjacent the opposite end, a lever pivoted at one end in said recess and having a free end to engage over the body part and hook, said body part having a cut-out part in one edge, means on the lever to engage a chain link or the like and adapted to engage in said cutout part, and a spring actuated locking dog positioned intermediate the sides of the body part and projecting beyond the edge of the body part, and said locking dog having an overhanging part to engage over the lever, substantially as and for the purpose described.

4. In a hame fastener, a body part having a recess intermediate its sides, a lever pivoted to said body part and adapted for connection to a chain link or the like, a hook having an extended body part adapted to it against one end of the body part and having a flange projecting therefrom and adapted to fit in the recess of the body part, the said flange having a recessed part, and a locking dog pivoted to the body part and projecting through said recess of said flange, said lever having an engaging part adapted to be engaged by said locking dog.

5. In a haine fastener, a body part having at one end a curved hook, the bill of which oflers no obstruction beyond the lower edge of the body part, a lever pivoted adjacent the upper edge of the body part at the end thereof opposite the hook, the operating end of the lever being adapted when in closed position to rest upon the back of the hook, and said lever having in termediate its ends a recess, a link pivotally secured tothe lever intermediate its ends, and a spring held locking dog positioned on the body part adjacent the upper edge thereof and extending in a direction opposite to that of the bill of the hook, said re cess of the lever being adapted to receive 'the dog in the closed position of the lever between the sides at the opposite end of the body part and mounted on the latter -for pivotal movement, a link connected with the lever intermediate its ends, and locking `means interposed between the lever and body part.
